Polar lipid mixtures, their preparation and uses

Abstract

Disclosed herein are polar lipid mixtures, comprising glycerophospholipids such as phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylserine (PS) and phosphatidyl-inositol (PI), and sphingolipids such as sphyngomyelin (SM). Most importantly, the ratio of phospholipids in said mixture is comparable to that of HMF, and is represented by SM>PC>PE>PS>PI or SM=PC>PE>PS>PI. Processes for the preparation of said mixtures and uses thereof are also described herein.

The invention claimed is: 
     
       1. A man-made lipid preparation consisting of a mixture of the following natural, extracted, polar, bovine milk glycerophospholipids: bovine phosphatidylcholines (PC), bovine phosphatidylethanolamines (PE), bovine phosphatidylserines (PS), bovine phosphatidyl-inositols (PI), and bovine sphingomyelins (SM), wherein in the mixture the relative ratio by weight is SM>PC>PE>PS>PI and the percent by weight is:
 SM, at least 10% w/w; 
 PC, at least 7% w/w/; 
 PE, at least 4% w/w; 
 PS, at least 2% w/w; and 
 PI, at least 1% w/w.
